Interests
One of the most important motivator is INTEREST. Your personal interest over your goal is a great factor to keep you motivated and succeed. Your burning desire over a thing or a goal keeps you focused and forget about the word failure. But if your goal is not something personal, but rather driven by other people, perhaps your parents or your family, you just force yourself to do it because of them and not because of your personal interest. You are just like dragged from your seat to do a task you never meant to do. These types of goal setting are less likely to succeed especially if it contradicts on your own goals.
In setting your goals, it is important to consider your own desire for that goal. If other people drove you to that goal, it is ok as long as you have the desire for it as well. Once you do not have the desire or the interest towards that goal, you tend to procrastinate and that goal will be kept hanging. Especially if you have other goals in life, you will prioritize those that caught your interest.
Motivation makes your way easier to reach your goal. You may feel it is very easy but if you analyze it, you have done a difficult task already, one which you couldn’t imagine yourself doing. But because you are motivated, you didn’t feel the difficulty and the pressure.
